Im virgin, only had two depo-provera shots, now off for 9 months. menstrual is irregular when can i ovulate again? and when can this shot wear off?

Up to a year: Unfortunately, a couple of Depo-Provera shots may hang around in your system for up to a year. If you are having some irregular periods, then at least that says your system is "waking up" from being put to sleep... It is difficult to say whether or not you are having ovulatory cycles -- you could be now, but just with irregular periods. This will eventually straighten out.
